A CENTURY OF QUANTUM PHYSICS

Quantum physics revolutionized our concept of matter, energy and the universe. 

Our understanding of the quantum world began with Niels Bohr's discovery of the quantum atom in 1913.

This field emerged to explain the common sense-defying behaviour of atoms, molecules and light at the smallest scales, forming the foundations on which we have built one of the greatest and most successful theories of all time — quantum mechanics.

He saw that electrons were behind the electric currents flowing in wires, the red hot glow of molten iron, and the production of light from electric discharges in gas-filled tubes.

Bohr took the important elements of the emerging theories to explain all these different things, invented some new quantum mechanical principles and made it all work.
